In our never ending quest to expose fictional cinematic incompetence, we're going to take a hard look at characters from The Lord of the Rings trilogy who screwed the pooch at key moments.
These are moments so infuriatingly inexplicable that they make us want to throw our $100 Platinum Series Special Extended Edition of the trilogy out window and watch Willow three times in a row instead.

But somewhere between hacking the worm to bits and letting him leave on a horse carrying information that will be incredibly valuable to your enemy there are other, perfectly good choices. Put him on trial. Put him in jail. Or, if even that is too merciless for Tolkien's heroes (and keep in mind, no Orc is ever shown that kind of mercy) then just let him hang around and make sure he isn't allowed to leave and tell Saruman everything he knows.
"Boss, you will not believe what just happened.
Aragorn's judgment is so poor it'd make Sun Tzu prolapse in his grave. And even his rationale--"enough blood on has been spilled on his account"--is bullshit. Wormtongue's release DOES lead to blood being spilled. A whole freaking water park of hemoglobin, in fact, as it was Wormtongue who told Count Dooku about the weak point in the walls of Helm's Deep.
